Here's how I get album art for a song:
Cursor cursor = getContentResolver().query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
new String[] {MediaStore.Audio.Albums._ID, MediaStore.Audio.Albums.ALBUM_ART},
MediaStore.Audio.Albums._ID+ "=?",
new String[] {String.valueOf(albumId)},
null);
if (cursor.moveToFirst()) {
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
// do whatever you need to do
}
albumId
refers to MediaStore.Audio.Media.ALBUM_ID
for that song.
If you're are looking for album art for a particular song (rather than in a list of albums), as far as I know it's a two-stage process since ALBUM_ART
is a property of MediaStore.Audio.Albums
and is not available directly as song metadata.
